More information is needed.. What type games are they in? More information is always better, just as pictures are helpful..

I forget what model they are ... 150 rings a bell ....: BU activate has a dip for it ....with it activated machine looks for it but don't cycle it on boot up or anything like that ... it's like it's not there ... I tried different heads does the same thing It's using a WBA 13Are these units bench testable ?? I have a bunch of them here ??

Once again. We can't give you advice without the information like make and models. More then likely if the battery's were dead and changed, then you more likely then not are going to need a set or a key/clear chip. Just flipping a dip switch is not going to actavate a bill acceptor. That's why I said pictures are helpful.

Well now that you know they are Sigma 300, you might want to post under the Sigma section and ask if anyone know how to actavate those bill acceptors.

Attached below is a Quick Reference guide for the WBA bill acceptors. It has instructions on how to test the WBA unit. The WBA has a set of dipswitches on the side, all of the dipswitches should be OFF for normal operation. When troubleshooting a bill acceptor you should use the $1 bill because other bills may not be recognized, depending on the age/rev level of the software inside the bill acceptor.

There may be a setting in the machine's Setup/Preferences screens to enable the bill validator but I don't know about that. You'd need someone familiar with this Sigma machine to advise about that or get a copy of the manual. For a donation (small or large) to the NLG website you can get access to the download area, there are several Sigma manuals available.

As you probably know but just to make sure, the software in the WBA must be the same "ID-XXX" number to match whatever the slot machine uses for communication with the bill acceptor. If someone has been swapping things around and you have a WBA in the Sigma machine that used to be in an IGT machine then it probably won't work. Look for stickers on the WBA with something like "ID-XXX".

If the machine is a Sigma 360 and it has the mpu board shown below there are two blocks of dipswitches on the mpu board. DS1, position 10 should be set ON to enable the bill validator. This old drawing of a Sigma SG300 mpu might be for a different board than the one your machine has. If so then disregard this information.

that is the board and setup in this machine, I ended up diabeling the DBA by turning the dip off cause it didnt see it and was throwing an error .....if i remember right it just said bill acceptor error on the VFD...I dont believe these were ever messed with I have a handful all of the same model .....I find it hard to believe all are froze stuck or bad, Im leaning toward a comm prob between the machine and the DBA or possibly no power to it, also which I doubt, having that prob on 3 machines i dont see plausible... these came right from a wholesaler who took them right off the casino floor a few years back...Id love to get a pinout of these and power them up with an external powersup and see what they do

3 units all i get is on power up led 1 then a second or 2 later led 2 comes on .... no error flashes.... put the unit in test mode with the dip 8 and same thing ... 3 units 3 diff heads.... took the working head out of mu IGT and its same scenario....... must be either an inhibit line active or all 3 transports a dead... hard to believe but could be ..... im open to any suggestions

I know very little about the WBA units but seems like I heard the software for them is located in the transport and not in the head. Can you try the Sigma WBA heads in the IGT machine that has a WBA setup? That might show you that the Sigma WBA heads are good.

Also, have you checked for security switches around the cash storage cans, cash compartments? There is sometimes more than one security switch. If the cash can/cash box has been removed, or if it isn't seated right or maybe if the cash access door isn't locked then the bill acceptor won't work. I'd look for something in common with all 3 machines that is wrong, missing, disconnected etc. Like you say, if these WBA units are original to these machines they should work, so look for something related that happened to all 3 machines.

Here is a drawing showing the bill acceptor wiring. It looks like it has several security switches.

im gonna poke there next cause i have this dba on the bench and it works ok in test mode .... gotta be a interlock sw open on the cassette or something like that...... those are easy enough to bypass .... if i tie the (2) 12v's and the (2) grounds together should work fine with out any safety switches hooked up .... if you're gonna be up a few mins sand by im gonna do that now

I don't know specifics on Sigma machines but in general the security switches around the bill acceptor, cash storage compartment and cash box often cause annoying problems. Everything has to be installed and seated properly, doors shut, etc. Are the WBA units updated to latest software, or do you expect they will only work with older bills?

I got it to work by tying both 12v and both grounds together on the dba harnes ....doing so eliminated all security switches related to that area......it accepts older bills at the moment ..... I have SW here for it not sure how new it is ....... I also have an updated unit in my IGT ....I can copy and use that software if needed .... that's what I'll do today

keeps giving "bill val error" I can't get to clear ..... which is an error according to the manual either bill path jam or cassette full..... neither is the case.........tried 3 diff heads and 3 diff transports all give same error....they all work fine in test mode, accept and stack fine. machine in i/o test shows no open switches for val door or cassette missing.... DBA initializes on boot up but wont accept......I turn JP key to clear error says resetting DBA but goes back to same, not accepting and giving bill val error ...........urgggggggggghhany ideas

Does the IGT WBA use the same software that the Sigma uses? I figured they were different.

In your message you said the WBA in the Sigma was working ok (with old bills) once you bypassed the security switches. That tells me that one of the security switches was probably causing the original problem. Did you find which one was the culprit? Also, did you start getting the latest error ("bill val error") after you changed the software in the WBA? If the manual you are referring to that you are using for interpreting the error messages is the JCM WBA manual/quick ref guide then keep in mind it assumes you have the correct WBA software installed for the slot machine the WBA is installed in. If that isn't the case then all bets are off. The WBA in the Sigma machine needs to have Sigma compatible software and I'm not so sure that you can use the IGT WBA software in a Sigma, maybe someone here will give an opinion on this.

yeah theres no comm on the IF board leds from the dba with the newer software from the igt.... the others communicate fine...... but it quit woring .... now it wont accept anything wont even take them in , it cycles and initalizes but thats it, i tried an interface board from another machine as well as a ribbon cable still no go

Do any of the WBA units work in the Sigma after you loaded them with the newer IGT WBA software? (meaning: the IGT WBA software is compatible with the Sigma machine?)
